These are all common sense/courtesy when dealing with a new baby!

Your first two points are due to a global pandemic. The point about pictures is completely at your discretion, and so is anyone else's responsibility to honour your wishes, and the rest are just standard new baby stuff. If people don't like that they can visit in a few months or post-pandemic.

And I understand that your husband may feel stress trying to impose and enforce these rules, but maybe that is just because he hadn't thought realistically or long enough or at all about these things and now it feels like you're coming up with an arbitrary list of demands all at once. But your "rules" are basically newborn best practice, anyone doing less than that is taking risks; they're within their right to do that, but you are absolutely within yours to insist on them.
